Patent GB-414248-A (GB)
Abstract: 414,248. Calculating-apparatus. MERCEDES BUROMASCHINEN-WERKE AKT.- GES., Benshausen, Prussia, Germany. Oct. 25, 1933, No. 29549. Convention date, Nov. 5, 1932. [Class 106 (i).] Clear signals and marks.- A clear sign impression mechanism for a typewriting- calculating machine comprises a member for feeling the totalizer pinions, which member is normally locked but is freed by a mechanism acted upon by the feeling member to release the clear sign key for operation. The invention is shown applied to a machine of the Mercedes type with a plurality of totalizers 7 mounted on a bar 6, Figs. 1, and 3 on a travelling carriage. The end totalizer 7r has pivoted to its casing a feeler plate or member 46 with prongs 49, Fig. 4, for engaging the totalizer pinions. The plate is held in disengaged position by a locking member 54 engaging a projection 15 on the plate. During the tabulating movement of the carriage, in the operation of recording the total by setting the amount up and restoring the wheels of the totalizer 7r, the projection 15 co-operates with a pin 14 at one end of a lever 13 the other end of which engages the horizontal part of an inverted T-shaped slot in a link 18 pivoted to the clear sign key 26. As the carriage tabulates to the units column position of the totalizer the pin 14 coacts with the projection 15 and is displaced to move the end 22 of the lever 13 into the other part of the horizontal arm of the slot maintaining the key 26 locked against depression. On tabulating to the next position the pin 14 co-operates with the lower edge 55a of the locking member 54 and raises it to release the feeling plate 46. If the amount has been correctly recorded the plate 46 is rocked so that the prongs enter into a recess of the zero tooth of each totalizer pinion and set the end 22 into the central position of the slot to permit lowering of the link 18 on the depression of the clear sign key. If the amount is not correctly recorded the end 22 is not moved sufficiently to permit the link 18 to be lowered. Specification 380,551 is referred to.

Title: Crane load warning system
IPC: B66C15/06
Filed: 1974-09-25
Abstract: 1476525 Load-monitoring device EATON CORP 25 Sept 1974 [23 Oct 1973] 41648/74 Heading G1N [ Also in Division B8] A load monitoring and warning device for a crane includes a load cell 10 in one cable of a main lifting system, an alternative cell 11 in an auxiliary system can be selected by switch 12. The output from the load cell is compared with a reference signal so that when the load on the cable falls to a set proportion of the static load an output signal operates alarms such as a warning light 34 or an audible alarm 36. Thus warning is given if a load catches on an obstacle while being lowered. The reference signal is set by a digital switch 37 and is supplied to a switch 23 at input 24 and in a first position of the switch 23 is connected to input 28 of a differential amplifier 31, the signal from the load cell being connected to input 27. The warning device will then be operated if the load exceeds a value corresponding to the setting of switch 37. This position of the switch is used in lifting after which the reference signal is adjusted by operation of switch 37 to equal the actual load signal on lead 29. Switch 23 is then moved to connect lead 26 to input 27 and lead 29 to input 28. The alarm will then be energized if the load falls below the static load by a fraction determined by resistors R8, R9. The output of the load cell may also be used to provide a continuous display of the load on an indicator 19, and may be fed to another differential amplifier 22 which gives a warning if the load exceeds the maximum allowable value.

Abstract: 917,508. Control of two D.C. motors; controllers. YALE & TOWNE MANUFACTURING CO. Dec. 9, 1960 [May 9, 1960], No. 42426/60. Class 38 (3). [Also in Group XXXI] An industrial truck comprises a pair of traction units mounted for angular movement relative to the truck, each unit including a wheel and reversible electric motor, a controller for the motors, and means whereby the controller cannot drive the motors at different speeds unless the traction wheels are aligned longitudinally of the truck. The controller 11 has handle 34 adapted for universal movement and co-operating with spring-biased pins 38. Contact assemblies 45LF-45RB are actuated by the pins 38 to close the motor circuits, by successively short-circuiting resistances through contactors. The contact assemblies are actuated in pairs to drive the traction motors at equal or unequal speeds and in the same cr opposite directions. Alternatively, each assembly may be actuated individually. When solenoids 54 are energized, however, they exert upward pressure on rods 49 to restrain the handle 34 so that it can pivot sidewise only to depress contact assemblies 45LF, 45RB, or 45RF, 45LB. Thus, the wheels are then drivable only in opposed directions and at the same speed. In addition, the truck has a steering-wheel 29 to rotate steering and traction units 16L, 16R, in opposed directions, a locking dog 63 enabling the steering to be locked when wheels 22L, 22R, are aligned longitudinally of the truck.

Abstract: 1,274,524. Magnetic storage arrangement. LICENTIA PATENT VERWALTUNGS G.m.b.H. 28 Aug., 1969 [22 Aug., 1968], No. 42848/69. Heading H3B. In a coincident current core store, switching currents are passed to a selected core location via a resistor and bridge connector transistor switches, the switches being controlled by a differential amplifier and the voltage rise across the resistor during selection being used to initiate a read strobe pulse. In Fig. 1, nine x drive conductors are shown for cores 129-137 and are electrically isolated from one another by diodes 120-128 and 146-154, the transistor switches being numbered 114-119 and 155- 160. A given x conductor such as that passing through core 132 is activated in known manner by pulsing the bases of a pair of transistors 115 and 158 or 117 and 156 dependant on the required current direction, the pulses being provided by the collectors of the appropriate ones of selection transistors 104-112. The current flows between a -24 volt rail and a 0 volt rail via resistor 165. The selection transistors are arranged in a differential amplifier configuration with transistors 103, 113, and have their emitters connected to a 5 volt rail by resistors 101, 102. Normally current flows through these resistors to the 0 volt rail via transistors 103, 113 and diodes 169, 170, but when a conductor is to be selected the potential at the base of the appropriate pair of selection transistors is made lower than that at the bases of transistors 103 and 113, and the current flows through the selection transistors to activate the required switches. This manner of commutation of current is stated to give rapid initiation of selection currents. When commutation occurs, a potential rise across coil 139 in the collector circuit of transistor 103 switches on a transistor 140 to connect the base and emitter regions of transistors 155-160, to ensure rapid turn off of current in the selected conductor, and a similar arrangement (not shown) is used for transistors 114- 119. The voltage rise across resistor 165 in series with the bridge switches is arranged in a gate circuit with a similar resistor for the y conductors and capacitor 164, Fig. 3 (not shown), and when the rise due to the last to be selected conductor is sufficient to switch on a transistor a read strobing pulse is initiated. The strobing pulse is switched off by a clock pulse. The - 24 volt rail is variable to counteract changes in magnetic core properties with temperature, the circuit operation being insensitive to such voltage changes.
